Dry bonito flakes are shelf-stable. Once rehydrated or incorporated into a perishable dish, follow standard food safety guidelines for perishable foods, ensuring they are not left in the danger zone for more than 2 hours.
Safe Handling
Store in airtight containers to prevent moisture absorption, which can lead to spoilage.
Keep away from direct sunlight and heat sources.
Always use clean utensils when handling to prevent cross-contamination.
Discard if any signs of spoilage are present.
